﻿/**
 * [FIXED][2.2.1 & 3.0 dev] "GridView.focusCell" will make a mistake on IE6
 * When I click a cell of editable-grid, the gridBody will scroll to Left.
 * But the grid DOESN'T have any scrollBar ---- the grid just has tow columns, the gridBody's width is smaller than gridPanel's 
 *
 * reference: http://www.extjs.com/forum/showthread.php?p=282928#post282928
